IR imaging is playing an important role in industry these days. However, the IR cameras only support low resolution for technical reasons. In this paper, we propose to use the visible camera as a guidance to super resolution the IR images. We setup a prototype of the IR-Color multi-sensor imaging system and construct a dataset including videos collected(More)
Spatial psychovisual modulation (SPVM) is a new information display technology, which aims to generate multiple visual percepts for different viewers on a single display simultaneously. After the proposal of SPVM, lots of efforts have been made and several applications (i.e., dual-view display system) have been implemented based on this technology. The(More)
This paper introduces a new information display system that can prevent the on-screen contents from being taken by cameras or camcorders without sacrificing visual qualities. The system is designed based on the idea of temporal psychovisual modulation (TPVM) with guidance from the concept of ‘window of visibility (WoV)’. TPVM utilizes the(More)
Oil and gas reservoirs can cause increased attenuation of seismic waves, which can be revealed by time-frequency analysis for direct detection of hydrocarbons. In this paper, a new method applying the empirical wavelet transform (EWT) in association with the synchroextracting transform (SET), named EWT-SET, is proposed as an improved time-frequency analysis(More)
